TreeGrid startEditingNew

[cirovladimir]

I wanted to start editing a new node when the user clicks a button. I found this article that explains how to do this. I wanted to leave an example here in case anyone wants to achieve this.
The node would be added to the tree if it's empty or as a child if a node was selected.

private ClickHandler btnAddCategory_onClick=new ClickHandler() {
		
	@Override
	public void onClick(ClickEvent event) {
		Record newRecord=new Record(JavaScriptObject.createObject());
		if(grdCategories.getSelectedRecord()!=null){
			Record selectedNode=grdCategories.getSelectedRecord();
			newRecord.setAttribute("idParent", selectedNode.getAttribute("id"));
		}				
			grdCategories.addData(newRecord, new DSCallback() {
					
				@Override
				public void execute(DSResponse response, Object rawData, DSRequest request) {
					if(response.getStatus()>=0 && response.getData()!=null &&response.getData().length>0){
						Record record=response.getData()[0];
						TreeNode parent=grdCategories.getData().findById(record.getAttribute("idParent"));
						if(parent!=null){
							grdCategories.getData().openFolder(parent);
						}
						int row=grdCategories.getRecordIndex(record);
						grdCategories.startEditing(row, 0, false);
					}
				}
			});
	}
};
